Mario Gotze has left the door open for a move to Liverpool and a reunion with Jurgen Klopp.

The German starred under Klopp for Borussia Dortmund before earning a move to Bayern Munich in 2014.

Gotze rejected the chance to head to Anfield when he rejoined Dortmund two years later, but has refused to rule out working with his old boss in the future.

"I decided to leave Bayern and Jurgen Klopp was interested in getting me to Liverpool. And I was also interested in working with him again," Gotze said in the DAZN documentary 'Being Mario Gotze'.

"It's still existing. He is a world-class coach and that's why it's always an option. I decided to join Borussia Dortmund, but it was not a decision against Liverpool or Jurgen Klopp. But on the contrary."
